Our family went to the Yellow Stone National Park last summer vacation. Our son, Tom, wanted to see bears there. And what an experience(经历)it was!

When we got there, we put up our tent(帐篷) and went to explore(探险). As we returned, we heard our daughter Susie cry out. And then we saw a bear go into our camp.

    Tom wanted his father to chase(追赶)him away. His father said, “No. It's dangerous to chase a bear. And don't let him chase you. ”Susie said, “What shall we do? Maybe we should climb a tree. ”Tom said, “No. We have to get him out of there. He might go to sleep in our tent. ”“Maybe we could make him leave if we put some honey outside for him to eat. ”Susie suggested. Then I said, “How are you going to get the honey? It's in the tent. ”We watched the bear go into the tent and heard him upset(翻倒; 弄翻)everything inside. “It's foolish for us to try to chase him away. ”said my husband, “Leave him alone and wait for him to come out. ”We waited, but the bear stayed inside. We had to sleep in the car that night.

    Jane Goodall is a famous scientist. For more than 40 years, Goodall lived mostly in Tanzania in East Africa, studying chimpanzees(黑猩猩).

    As a young child, Jane Goodall was interested in animals. She grew up in the English countryside and was always climbing trees or riding horses.

    When Jane was 23, she got a chance to go to Africa. Even though she had never been to college, she got a job with a famous scientist named Louis Leakey.

    One day Louis Leakey said he needed a volunteer. He needed someone to go to a lake in Tanzania to study a kind of chimpanzees. Jane was excited.

    On July 16, 1960, she began her exploration(探索).At first, the chimpanzees ran away from Jane. But with the passing of time, they got used to her being around.

    Every day, Jane would follow the chimpanzees, taking notes on their behaviour. She learned many new things about chimpanzees. She watched how a chimpanzee made a tool. She learned how some chimpanzees became good leaders. She watched animals get angry and get upset. She wrote everything down so others would understand animals as she did. She learned that if you pay really close attention to animals, you will understand what they are "saying".

Problems between parents and children are common. If you need to improve your relationship with your parents, you are not alone. To develop a better relationship with your parents, you should change how you think and do things. {#blank#}1{#/blank#}

Act first. Don't wait for your parents to try to improve the relationship. {#blank#}2{#/blank#} Be thankful to your parents. Think about everything that your parents have done for you. You are sure to feel thankful to them. {#blank#}3{#/blank#} Give them a nice gift or do some housework without being asked. They will be happy with you for these actions.

{#blank#}4{#/blank#} Talk to your parents about things that you care about and your feelings about these things. Often talk to them, and your parents can understand you better. If so, it's easy for them to discuss things that you are interested in and develop the relationship.

Accept that your parents are different. They grow up in a different situation with different technologies. {#blank#}5{#/blank#}Try to remind them of any problem in their relationships with their parents because of these differences.

Use these ways when you talk to your parents to improve your relationship with them.

Developed by US company OpenAI,ChatGPT has taken the internet by.storm. People can ask the robot to write stories and emails,translate languages,and answer all kinds of questions.It does this by drawing on information collected from a large amount of internet text.One breakthrough behind today's model is a network called Transformer.The GPT models built by Open AI combined Transformer with unsupervised(无人指导的)learning,which means that the models can learn by themselves without being told what to look at.

"One of the biggest problems with ChatGPT is that it comes back,very  confidently,with false information,"Michael Wooldridge told The Guardian.This means that ChatGPT learns information from various resources but it cannot decide what is true or false.Some argue that ChatGPT will be used to make fake news, spread falsities,or be used for ill purposes.

Andreas Schleicher thinks the chatbot will become a very powerful tool in the development of education.But he also mentioned,"There's a great risk that we'll just blindly follow the answers that we get from ChatGPT rather than question it and create new knowledge.If students are only as smart as a smartphone,it means educators are not doing enough.People should focus on developing human skills that actually are important,such as imagination and creativity."

Schleicher added that as a tool,ChatGPT is going to make learning much more interesting and powerful,but as a purpose and goal,humans need to work very hard to win that race with technology.

"Life is short, but there is always time enough for courtesy (礼貌);

— Ralph Waldo Emerson

 People love being polite. You might have noticed we are always saying"please", "thank you","excuse me", and"sorry".

 When making a request, you ask someone to do something for you. ▲, it may not help them in any way.

 Sometimes, you might make a request, and that request can be difficult for the other person to do. So it is necessary to make sure that you are being polite when making a request.

 To do this, you might include some words such as"can", "could", or"please" to soften(使温和) your approach. They may make it look like you are asking a question instead of making a request. However, don't worry — the listener will understand you.

 For example, if you are in a restaurant and say"I want the bill(账单)" to the waiter, your request will be considered very direct. You might use this kind of language if you are angry or have had very bad service. However, if you wish to sound polite, you might consider speaking like this:

"Can I have the bill, please?"

"Could I possibly have the bill, please?"

We can also use polite language to ask for permission(准许). For example, just sitting down next to someone without asking might be considered a bit forward (鲁莽的). If that person is waiting for a friend, you may create an uncomfortable situation. You can ask for permission first. For example:

"Would it be OK if I sat here?"

"Do you mind if I sit here?"
